Abstract: A photonic node includes a first circuit disposed on a first substrate and a second circuit disposed on a second substrate different from the first substrate. The first circuit is configured to route light signals originated from the photonic node to local nodes of a local group in which the photonic node is a member. The second circuit is configured to route light signals received from a node of an external group in which the photonic node is not a member, to one of the local nodes.

Abstract: Examples herein relate to optoelectronic assemblies. In particular, implementations herein relate to an optoelectronic assembly formed via a chip on wafer on substrate (CoWoS) process. The optoelectronic assembly includes a substrate, an interposer, and an electronic integrated circuit (EIC). Each of the substrate, interposer, and EIC includes opposing first and second sides. The EIC is flip-chip assembled to the first side of the interposer, and the interposer with the EIC assembled thereto is flip-chip assembled to the first side of the substrate. An overmold layer extends over the first side of the interposer and encapsulates the EIC. The overmold layer includes a cavity such that a region of the first side of the interposer is exposed. An optical component is positioned within the cavity and coupled to the first side of the interposer.

Abstract: In example implementations, an optical connector is provided. The optical connector includes a jumper holder, a base bracket, and an optical ferrule. The jumper holder holds a plurality of ribbon fibers. The base bracket is coupled to an electrical substrate to mate with the jumper holder. The optical ferrule is coupled to an end of each one of the plurality of ribbon fibers. The optical ferrule is laterally inserted into a corresponding orthogonal socket that is coupled to a silicon interposer on the electrical substrate to optically mate the optical ferrule to the orthogonal socket.

Abstract: Examples described herein relate to reducing a magnitude of a supply voltage for a circuit element of an optical transmitter device. In some such examples, the circuit element is a driving element that is to receive a first electrical data signal and to provide a second electrical data signal to an optical element that is to provide an optical data signal. A testing element is to compare the optical data signal to the first electrical data signal to determine whether the optical transmitter device meets a performance threshold. When the device meets the performance threshold, a regulating element is to reduce a magnitude of the supply voltage of the driving element.

Abstract: Examples herein relate to polarization diversity optical interface assemblies including a single mode optical fiber and first and second grating couplers disposed on a substrate. The first and second grating couplers are coupled to first and second waveguides, respectively. The assemblies further includes an optical connector to couple light between the single mode optical fiber and each of the first and second grating couplers. The optical connector includes a ferrule and a walk-off crystal. The ferrule is coupled to a portion of the single mode optical fiber. The walk-off crystal is configured to spatially separate the light into first and second orthogonal polarization modes prior to passing through the respective first and second grating couplers and/or combine the first and second polarization modes of the light prior to passing through the single mode optical fiber.

Abstract: In one example, an apparatus includes e first beam splitter having a first output and a second output. A first optical waveguide is coupled to the first output, and a second optical waveguide is coupled to the second output. A first tunable phase delay is further coupled to the second optical waveguide and has a third output. A first set of phase modulators is coupled to the first optical waveguide, and a second set of phase modulators is coupled to the third output of the first tunable phase delay. At least one of the first set of phase modulators and the second set of phase modulators includes a phase modulator that is driven to three or more distinct phase states. A second beam splitter has a first input coupled to the first optical waveguide and a second input coupled to the second optical waveguide.

Abstract: Systems and methods are provided for processing an optical signal. An example system may include a source disposed on a substrate and capable of emitting the optical signal. A first waveguide is formed in the substrate to receive the optical signal. A first coupler is disposed on the substrate to receive a reflected portion of the optical signal. A second waveguide is formed in the substrate to receive the reflected portion from the first coupler. A second coupler is formed in the substrate to mix the optical signal and the reflected portion to form a mixed signal. Photodetectors are formed in the substrate to convert the mixed signal to an electrical signal. A processor is electrically coupled to the substrate and programmed to convert the electrical signal from a time domain to a frequency domain to determine a phase difference between the optical signal and the reflected portion.

Abstract: Examples include a method for fabricating a grating mirror using a computing device that comprises calculating a target phase change across the grating mirror. The target phase change may correspond to a target wavefront shape in a beam of light reflected from a grating patter. The method may also comprise generating the grating pattern comprising a plurality of lines with line widths, line period spacings, and line thicknesses corresponding to the target phase change across the grating mirror using the computing device. In such examples, a set of coordinates may be generated using the computing device with each coordinate identifying a location of a line of the plurality of lines, a line width of the line, a line period spacing of the line, and a line thickness of the line.
